Question

Determine the missing term that should be in the empty box of the polynomial that will make the solution true.

Answer 1

Missing term = r²

Explanation:

Given:

6r⁴ + 4r + …. -2r⁴ + 3r = 4r⁴ + r² +7r

Find:

Missing term

Computation:

Assume missing term = A

So,

6r⁴ + 4r + …. -2r⁴ + 3r = 4r⁴ + r² + 7r

6r⁴ + 4r + A -2r⁴ + 3r = 4r⁴ + r² + 7r

4r⁴ + 4r + A + 3r = 4r⁴ + r² + 7r

4r⁴ + 7r + A = 4r⁴ + r² +7r

A = r²

Missing term = r²
